We examined the thermoelectric performance of Tl8GeTe5 at temperatures ranging from room temperature to 700 K. We prepared sintered samples and evaluated their thermoelectric properties. Although the electrical properties were not exceptionally high, Tl8GeTe5 exhibited the relatively high dimensionless figure of merit ZT, i.e., 0.19 at room temperature and 0.60 at 700 K, due to the low lattice thermal conductivity.
